Gamepad: Remove GamepadList and fix dropped connection event on startup (#31684)

Browse source 
* Replace GamepadList

* Fix initial gamepad connection event from gilrs getting dropped

* Fix gamepad reconnection issues, use MutNullableDom

* Reduce some repetition in handle_gamepad_events

* Address feedback, move some steps to navigator methods

* Refactor internal navigator gamepad methods

* Add note re: unused gilrs index, adjust navigator gamepad methods
